Enchant Equipment allows you to improve equipment in stages, resulting in increased unique stats.
You can tap on the [Equipment Modification], [Enchant] button from the main menu (≡) to view the current equipment Enchant stats and increased unique stats.
You can also view the amount of Enchant Scrolls you have.
You'll have a 100% success rate up to stage 3 Enchants, but there will be a chance to fail starting from beyond stage 3
A failed Enchant decreases the stage by 1.
However, you can prevent a decrease in stages by using Protectants.
Starting from stage 10 Enchants, the equipment stage will not decrease below stage 10 even when the Enchant fails.
